2024年8月1日 · This present study primarily focused on estimating the current groundwater status of agro-rich Murshidabad district using a GIS-based empirical approach including trend analysis of groundwater depth (2001–2021) by using Modified Mann Kendall test (MMKT) and Sen's slope estimator; the most prominent water level fluctuation (WLF) method employed i...

2022年1月1日 · Significantly, the average measured groundwater levels in the currently producing borewells (16 in number), all deeper than 165 m, is 177 m (bgl) which can be considered as the depth to the true groundwater level in the area.

2015年1月1日 · Over pumping for irrigated agriculture resulted in depletion in groundwater levels particularly in central, northern and southern parts of the watershed, where the water levels are more than 20 m bgl (meter below ground level).

Download scientific diagram | Groundwater level (m b.g.l.) plotted against depth of well (m b.g.l.) for the shallow piezometer network at Siersza (piezometers numbered P4 to P13). Data are...

Common Abbreviations: agl/bgl/mbd – above ground level/below ground level/metres below datum. OD – Ordnance Datum (sea level). Datum‐ a standard position or level that measurements are taken from, that may not be ground surface. AOD/BOD – Above Ordnance Datum/Below Ordnance Datum.

远海的再循环海水也主要用于中等深度（>1.5 至 100 m bgl）（咸水饱和）和更深深度（>100 m bgl）（新鲜地下水），这是从明显的电阻率对比中观察到的来自 VES。沿海水动力、大气补给、地下水位波动等因素均诱发了各层深度与海水的相互作用过程。

water level of the country ranges from 2 to 20 m bgl. To be more specific, in major parts of the country, water level is observed to be in the range of 5 to 10 m. Very shallow water level of less than 2 m bgl is also observed locally, in isolated pockets, in few states, such as Assam, Goa and Himachal Pradesh. In major parts of north-western ...

Groundwater level is a term that is used in a relatively loose way, normally referring to the level, either below ground or above ordnance datum, at which soil or rock is saturated. This is also referred to as the water table and represents the top of the saturated zone. Above the water table lies the unsaturated zone.
